PROBLEM TO BE SOLVED: To provide a scouring preventing tool for a water discharging port, supplying water without scouring the ground surface of a paddy field by water current at the time of supplying water to paddy fields from the water discharging port.;SOLUTION: This scouring preventing tool is set with a discharged water receiving body 11 laid on the place of the ground surface 6 to which water w falls down from the water discharging port 4 of a water-dividing concrete box 3, and a fixing part 12 unitedly set with the discharged water receiving body 11 and fixed to the ground surface 6. The discharged water receiving body 11 is set with outflow direction regulating parts 13 and 14. It is possible to prevent the scouring of the ground surface 6 by water w discharged from the water discharging port 4 with the discharged water receiving body 11. Furthermore, since the discharged water receiving body 11 is fixed to the ground surface 6 through the fixing part 12, the discharged water receiving body 11 does not begin to move by the impact of water w discharged from the water discharging port 4 and falling down on the discharged water receiving body 11.;COPYRIGHT: (C)2005,JPO&NCIPI
